The examiner's workflow,
with AI at every step
Goveda Pro follows the way patent offices actually examine: open a case, search prior art, assess unity, draft the opinion. It runs inside Claude or ChatGPT.

IV. Unity of invention
There are multiple inventions in this application, as follows. The claims are divided into the following 6 groups:
Group 1: Claims 1-10 (in full) and 35-36 (in part) relate to the use of Compound 1 for treating renal anemia, wherein Compound 1 is administered at least 1 hour or at least 2 hours before and/or after a second pharmaceutical composition comprising multivalent cations to maintain bioavailability or minimize a decrease in absorption of Compound 1.
Group 2: Claims 11-19 (in full) and 34-36 (in part) relate to the use of Compound 1 for treating renal anemia, wherein the dose of a co-administered statin drug is adjusted to maintain bioavailability of Compound 1 or to minimize, prevent, or control an increase in exposure to the statin drug.

3 analyses independently reached the same conclusion.
All three independent claims (1, 8, 18) share a specific common technical feature: a clamp with clamping finger(s) pivotably connected to a clamp base and a support ring moveable between first and second positions that urges the clamping finger(s) to pivot into engagement when moving from the first to the second position. None of the provided prior art documents (D1-D5) clearly disclose this specific clamping mechanism, so the shared feature constitutes a valid special technical feature linking all claims into a single inventive concept.
Claims 1, 8 and 18 are linked by the same specific clamp concept: pivotable clamping fingers mounted to a clamp base and urged into vessel-engaging positions by movement of a support ring. None of D1-D5 clearly discloses that support-ring/pivoting-finger arrangement, while the controller, actuator, cover, biasing, retaining and sealing features in the dependent claims are implementation refinements of the same inventive concept.
All independent claims (1, 8, 18) are linked by a common technical feature: a clamp mechanism comprising pivotable clamping fingers urged into engagement by a moveable support ring. The provided prior art does not disclose this specific mechanism, making it a valid Special Technical Feature. The claims simply cover different scopes and categories (apparatus and sub-assembly) of a single inventive concept.
Run the entire workflow inside Claude or ChatGPT
Connect the Goveda Pro MCP server once. After that you can create projects, pull the result of any step, and finish the written opinion without leaving the chat.

Built for examination
Trained on examiner written opinions
An IP-specialised model trained on historical examiner written opinions from patent offices worldwide — with particular emphasis on IPOS examination standards — for accuracy where it matters.
A Knowledge Base for every project
Keep NPL, patent documents, office actions and other reference PDFs with the case. Goveda Pro extracts each one once. You can check the extracted text against the original page, and Claude or ChatGPT can read the passages you need.

Search runs across 220M+ patents. When an application carries a WO / PCT number, Goveda Pro follows its family to the other offices and pulls in the citations those examiners already found.
Unity of Invention, assessed
A dedicated unity-of-invention assessment that runs on the search results, identifying the special technical features and the point where the claims stop sharing them.
